Abstract: There is provided a fan assembly comprising a fan body comprising an air inlet, a motor-driven impeller contained within the fan body and arranged to generate an airflow, and a nozzle mounted on the fan body, the nozzle being arranged to receive the airflow from the fan body and to emit the airflow from the fan assembly. The nozzle comprises a base that connects to an upper end of the fan body and encloses one or more electronic components of the fan assembly that are provided on an upper surface of the fan body.

Abstract: The Mission Metric System is an original guiding utility for leaders to identify, measure, and act upon their organization's capacity to achieve mission. The Mission Metric System receives survey(s) and a value/mission statement; instantly presents a dashboard of measures; and instantly recommends leadership actions.

Abstract: Systems, apparatuses, methods, and computer programs for detecting anomalies to identify coordinated group attacks on computer networks are provided. An anomaly graph of a network including nodes, edges, and an indegree of the nodes in the anomaly graph may be determined. Nodes with an indegree of at least two may be designated as potential targets. Nodes with no incoming connections may be designated as potentially compromised nodes. The designated potentially compromised nodes may be outputted as potentially associated with a coordinated attack on the network when the potentially compromised nodes connect to one or more of the same potential target nodes.

Abstract: A mainshaft assembly for a gearbox and a gearbox embodying such a mainshaft assembly are disclosed. The mainshaft assembly comprises a mainshaft, and several drive gears, each carried for rotation about the mainshaft, each drive gear having a different number of teeth. The assembly includes first and a second hub, each being associated with a respective drive gear, each hub having a dog ring operable to selectively couple with the drive gear causing it to rotate with the hub or uncouple from the drive gear to allow the drive gear to rotate with respect to the hub. A respective drive connection means comprising a cage and rollers is associated with each hub and is operative to connect or disconnect the hub to the mainshaft for rotation with it or to allow rotation with respect to it.
